Abstract: The present invention relates to a cursor control system, including a first electronic device, a second electronic device, and a mouse. The mouse is wirelessly connected to the first electronic device and the second electronic device and may move a cursor on a first working desktop corresponding to the first electronic device or a second working desktop corresponding to the second electronic device. When receiving a drive signal from the mouse, the first electronic device displays a jump image on the first working desktop. When the cursor is moved to the jump image, the mouse may transmit a switching signal to the second electronic device according to a masking signal from the first electronic device, so that the second electronic device can display the cursor on the second working desktop.

Abstract: An anti-theft system and an operating method are provided. The anti-theft system includes a wearable device and a portable electronic device. The wearable device includes a first wireless module and a first processing module. The portable electronic device includes a second wireless module, a second processing module and a positioning module. The first wireless module and the second wireless module are in a wireless connection with each other. The second wireless module detects a received signal strength indicator value of the wireless connection. If the received signal strength indicator value is lower than a predetermined signal strength value, the positioning module is enabled to generate plural position data within a predetermined time period. Moreover, the second processing module calculates a displacement of the portable electronic device according to the plural position data and determines whether a warning mode is enabled according to the displacement.
